In early May, I received the Qualcomm Innovation Fellowship 2019 for my ongoing research on adversarial robustness of deep neural networks. After an initial application round, I was invited to the University of Amsterdam’s Science Park for the finalist round. The winners were selected based on a short research talk including questions from Qualcomm researchers.

During my master thesis I partly worked on OctNets, octree-bases convolutional neural networks for efficient learning in 3D. Among others, I implemented convolutional batch normalization for OctNets. This article briefly discusses the implementation, which will be available on GitHub.

Obtaining high-quality visualizations of 3D data such as triangular meshes or occupancy grids, as needed for publications in computer graphics and computer vision, is difficult. In this article, I want to present a GitHub repository containing some utility scripts for paper-ready visualizations of meshes and occupancy grids using Blender and Python.

Our CVPR’18 follow-up paper has been accepted at IJCV. In this longer paper we extend our weakly-supervised 3D shape completion approach to obtain high-quality shape predictions, and also present updated, synthetic benchmarks on ShapeNet and ModelNet. The paper is available through Springer Link and ArXiv.

In September, I received the STEM-Award IT 2018 for the best master thesis on autonomous driving. The award with the topic “On The Road to Vision Zero” was sponsored by ZF, audimax and MINT Zukunft Schaffen. The jury specifically highlighted the high scientific standard of my master thesis “Learning 3D Shape Completion under Weak Supervision”.

ARTICLE

Based on the Torch implementation of a vanilla variational auto-encoder in a previous article, this article discusses an implementation of a denoising variational auto-encoder. While the theory of denoising variational auto-encoders is more involved, an implementation merely requires a suitable noise model.

ARTICLE

After formally introducing the concept of categorical variational auto-encoders in a previous article, this article presents a practical Torch implementation of variational auto-encoders with Bernoulli latent variables.

ARTICLE

After introducing the mathematics of variational auto-encoders in a previous article, this article presents an implementation in LUA using Torch. The main challenge when implementing variational auto-encoders are the Kullback-Leibler divergence as well as the reparameterization sampler. Here, both are implemented as separate nn modules.
